Understanding Checksums
🔍What are Checksums?
Checksums are unique digital fingerprints that help verify file integrity. Even a tiny change in the file will produce a completely different checksum.
- Detect file corruption
- Verify download integrity
- Confirm file authenticity
- Monitor file changes
🛡️Security Levels
- MD5: Fast but not secure (legacy use only)
- SHA-1: Deprecated for security applications
- SHA-256: Secure and widely used
- SHA-512: Maximum security, larger hash
Common Use Cases
📥
Download Verification
Compare checksums to verify that downloaded files haven't been corrupted or tampered with during transfer.
🔐
Password Hashing
Generate secure hashes for passwords and sensitive data (though specialized algorithms like bcrypt are preferred).
📊
Data Deduplication
Identify duplicate files by comparing their checksums, useful for backup systems and storage optimization.
